can not run CUDA sample with GTX1050Ti with Max-Q in ubuntu16.04

After installing cuda10.0 , with command “nvcc -V” I get
“nvcc: NVIDIA ® Cuda compiler driver
Copyright © 2005-2018 NVIDIA Corporation
Built on Sat_Aug_25_21:08:01_CDT_2018
Cuda compilation tools, release 10.0, V10.0.130”.

While running samples “0_Simple/asyncAPI” and “…/cdpSimplePrint”, I got error
"CUDA error at …/…/common/inc/helper_cuda.h:708 code=35(cudaErrorInsufficientDriver) “cudaGetDeviceCount(&device_count)” "

then I check “nvidia smi” and the output is as follows

Something is wrong since "CUDA Version: N/A "

Also,I’m installing Pytorch and "torch.cuda.available()"got false.

Any Suggestions would be appreciated.

By the way,I installed cuda10.0 with deb(local) and no error reports.

Since there is no reply I just “sudo apt-get purge nvidia*” and “sudo apt-get install cuda” to install again and this time it works.
